SASH LOCK.

Application led January 8, 1923.

To all willem z'zmay concern.'

Be it known that I. FRANK C. Goni-ruina citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful lmprovements in Sash Locks; and l do hereby declare the following t-o be a full, clear, and exact description of the invention, such will enable others skilled in the art to which it appert-ains to make and use the same.

This invention relates to improvements in window sash fasteners, and has for its object the provision of simple and effective means for locking the two sashes of a window against relative movement.

A further object in view is the production of a simple and effective means for accomplishing this'result by inexpensive apparatus which is capable of either permanent mounting or portable use.

With these and further objects in view as will in part hereinafter become apparent and in part be sta-ted, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claimed. Y

1n the accompanying drawings,-

Figure 1 is a vertical, central section through the sashes of a window, parts being broken away, and the present improved lock being seen partly in longitudinal, central sec tion and partly in elevation.

Figure 2 isa side elevation of the lock or fastener detached.

Figure 3 is a similar view of the same with the locking wedge shown as swung laterally, as during the act of application or removal.

and 2 indicate respectively the upper and lower sashes of an ordinary window. An elongated frame 3, preferably of sheet metal, is provided with tabs l, 4, which are pressed into the material of the sash 1 so as to retain the frame 3-at anyvrequired elevation in the length of the sash 1, according to the distance sash 2 is to be permitted to be opened for purposes of ventilation while limiting the opening for preventing unauthorized access. The frame 3 is provided at its upper end with a downwardly-opening pocket 5 and at its lower end with an upwardly-opening pocket 6. Cooperating with the frame 3 is a locking wedge 9 having at its upper end aA longitudinally-extending tongue 11 and at its lower end a similarly extending tongue 10. ylhe pocket 6 terminates in an upstanding lip or flange 7, preferably formed integral with the pocket 6, the said pocket, as

best seen in Figure 1, being relatively shallow and the openings 8, 8, at the sides of the lip 7, permitting of the edgewise access of the tongue 10. The tongue 10 is rounded at its lower end and adapted to seat in the pocket 6, while the tongue 11 extends into the pocket 5. Pocket 5 is of a length tofreely accommodate tongue 11. The distance from the upper edge of the lip 7 to the lower edge of the pocket 5 is greater than the length of Wedge 9 but less than the distance from the upper end of wedge 9 V(not including the tongue portion 11) to the lower extremity of the tongue 10, whereby the wedge` 9 may be slid from its lowered position,- as seen in Figure 2, vertically until the upper end of the wedge strikesV the lower edge of pocket V5 without bringing the tongue 10 linto position capable of movement outward away from the frame 3,- because the lower portion of the tongue 10 will still underlap the upper portion of the lip 7. However, when the wedge 9 is so elevated, if otherwise free, it may be swung edgewise with a movement of the tongue 10 through one or the other of the openings 8, this edgewise movement, however, being accomplished only after a slight outward movement rof the wedge to cause the wedge to free itself from the edges of the frame 3. As seen in Figure 1, it would notbe possible for the wedge 9 to be movedv 'niovenient in the direction of opening.

lowered, the wedge may he moved in an inward or lateral direction until free troni the edges of the frame 3, sin e` the pockets 5 and 6 are of suiiicient width to allow this vement of the wedge.

The operation is fairlj,T obvious andinaj; he loriel'ijY stated as follows:

The freine 3 beingA afiixed to the sash 1, the wedge 9 ha its tongue l1 introduced into the pocket after the manner seen in Figure anc lien the wedge is swung edgewiso nniil the togne 10 nnderlaps the lip 7, wheienpon :i .edge is dropped and the tongue 10 seats itselie in the pocket 5. After thus assenihled, the lock is i'eadj' iozf operation, and when the ei tor lifts the sash 2 until it strikes th 'loe 91 the is i wedge will he inoif'ed ndmal-.liY and pressed laterallyY to the edition indice-ted in Figure 1., wherennon the sashes will be eiectively locked against 'ther relative To render the sashes free tor eoniplete opening, it is onli/vv neeessari' lower the 2 and remove the wedge 9 hi: first lining' it and then swinging it edo'ewise to the posi.- tion seen in Figure 3, and then withdrawing the tongue 11 from the 1goei-:et 5.

In Figures il to 9 inclusive are shown slighl7 Varied embodiments?, the principal variation consisting` ofl the provision of a deeperpoelret at the lower end or the wedgerecelving frame, while omitting the lateral openlngs or passages, whereby the space between the lower .and npper pockets einst he snfhcientlj-,fv increased to allow escape. with an inward movement of the wedge and its lowei.` tongue from the lower pocket, lilore in detail, the structures shown in` l? ares iff:

The iran'io 13 is in the foi-in or a solisten.- tialljffiat onen frame.. as showin and niej: he secured hy laterally ended pointed tahs 14, 14, iol-ined integral with the 'freine and designed to he forced into the. material of the sash l 'for securing' the fr-aine in place. The frame 13 is for ied at its upper and lower `ends with outward i' formed, preierahly stamped. pocli-ets 1 .and 16Y the npper 'pocket one/ning downwardly and the lower pocket openingT upwardly. Cooperating with the 153 is the locking weiilgge 17. The wedge 17 niai he rined o? an?? per end of the wedge at that iace contesov ing with the 'face olthe sash 1 or the frame Leense 'the frame is not in the forni of a ling tai) or tongue asily within the 'e7 is introduced by the insertion or Vthe tongue 18, the wedge long the length of the frame Der end contacts 'with the edge of nool'et 15, as indicated in The lower end of in a oownwardly Y 19 adepted to slide oekeli 16. rl"he wedge 1T is inf igageinent with the frame yion olf the tongue 18 into inoifeinent of the wedge to e position seen in Figure 5,
